Three-way zone lock with actuator - 6/4 "M IVAR.MODULO PLUS 3

Product detailed description

This three-way zone lock with actuator is commonly used in commercial and industrial heating systems to manage flow distribution across multiple zones. Installers and system designers typically integrate it into hydronic heating systems where precise temperature control is required. The device is suitable for applications such as underfloor heating, large commercial buildings, and industrial process heating. It enables the system to maintain different temperature settings in separate zones by directing flow through the appropriate branch.

The actuator operates by rotating the valve through 180°, allowing for full opening or closing of one of the two outlets. The system is designed for use with external threads and requires careful alignment during installation to ensure proper sealing and operation. The valve is particularly suited for environments where the system may be exposed to low temperatures, as it is rated for operation down to -40°C.

Technical parameters

Material	nickel plated brass CW617N
Operating temperature	-40 °C
Nominal pressure	PN 40
Supply voltage	230 V
Code	I01425712
Brand	IVAR

The operating temperature range from -40°C to +100°C allows the valve to function in both cold and hot environments. The PN 40 rating ensures it can handle medium to high-pressure systems, making it suitable for pressurised heating circuits. The 230 V supply voltage is standard for many European electrical systems, and the 4 VA power input indicates low energy consumption. The 28 Nm torque ensures sufficient force to operate the valve under normal system conditions.

Installation and connection

The valve is installed using external threads (MMM) and must be aligned with the correct orientation to ensure the actuator operates correctly. The installer should verify that the pipe connections are clean and free of debris before tightening the fittings. Common installation errors include incorrect thread orientation or failure to align the actuator with the valve stem. It is important to check that the actuator is mounted in a position that allows for full rotation without mechanical interference. The IP50 and IP55 ratings depend on the mounting position, so the actuator should be installed in a location that minimises exposure to dust and water.

Compatibility and accessories

This three-way zone lock is compatible with standard heating systems that use external thread connections and operate at 230 V. It is typically used in conjunction with thermostats and control systems that manage zone temperatures. No additional accessories are required for basic operation, but installers may need to order control wiring or mounting brackets depending on the system configuration.

Technical background for designers

The valve operates on a three-way mixing principle, allowing flow to be directed between two outlets depending on the actuator position. The nickel-plated brass body (CW617N) provides good corrosion resistance and mechanical strength, making it suitable for long-term use in heating systems. The actuator is designed to integrate with standard control systems, and the 120-second time constant ensures smooth operation without sudden flow changes. The service life and efficiency of the valve depend on the quality of the installation, the cleanliness of the system, and the absence of excessive vibration or pressure surges.

Service and operation

The valve requires minimal maintenance under normal operating conditions. However, it is important to periodically check for signs of wear on the actuator and valve stem, as well as for leaks at the thread connections. The system should be inspected for proper alignment and operation after any major system changes or maintenance work. No scheduled service intervals are specified in the technical data.

Frequently asked questions

Can the actuator be connected to a standard thermostat?
Yes, the 230 V actuator is compatible with standard thermostats that provide a switching signal to control the valve position.

Is the valve suitable for use with glycol-based heating systems?
Yes, the nickel-plated brass body is compatible with glycol-based media, provided the concentration and pH are within standard limits.

Can the valve be installed in a vertical position?
Yes, the valve can be installed vertically, but the actuator must be mounted in a position that allows for full rotation and proper sealing.

What is the maximum allowable pressure for this valve?
The valve is rated for PN 40, which corresponds to a maximum allowable pressure of 40 bar at standard operating temperatures.
